12 GeV Upgrade
Work is well underway in both the North and South Linac Service buildings to provide additional cooling capability. In Hall C, assembly of the support structure for the new Super High Momentum Spectrometer has also begun. Note that new construction work areas have been established, which will require additional Personal Protective Equipment for entry, and access will be restricted to those having a need to be there.
Center for Theoretical and Computational Physics
Nucleon off-shell effects can play a significant role in nuclear processes. A new Theory Center paper presents an off-shell extrapolation of a Regge model describing nucleon-nucleon scattering. The off-shell model is used to calculate deuteron electrodisintegration cross sections, and comparisons are made with data from Jefferson Lab experiments.

Environment, Safety, Health and Quality
A particular feature is that if any part of your body can "break the entry plane" into the space, it is considered an entry into that space.
If you encounter a situation or a space with a sign (or painted warning) indicating that a Confined Space exists, and you have not been properly trained (SAF907), do not enter the space. Remember this is different from an Oxygen Deficient Hazard (ODH) assessment. For more information about Confined Spaces, see ES&H Manual Chapter 6160 Permit-Required Confined Space (PRCS) Entry Program or the OSHA website.
Computing and Networking Infrastructure
CNI Systems Maintenance Period Set for July 16, 5-7 p.m.

Tracking Thomas at Jefferson Lab
Silvia Niccolai, Samika Hawkins, Jacob Pomeranz, Susan Brown and DeAnn Maddox correctly guessed the location for July 3. Honorable mentions go to Michael Haddox-Schatz, Harry Fanning, Narciso Gomez, Sam Holben, Brita Hampton, Dick Owen, Buddhini Waidyawansa, Carlos Ayerbe-Gayoso, James Thomas and John Root. Check out Tracking Thomas on flickr for a better view of his last location and this week's new mystery photo.
